JOE Ledley and Dwight Gayle will undergo late fitness tests ahead of Palace's match with Tottenham on Saturday.
Welsh midfielder Ledley missed Tuesday's 1-0 defeat to Aston Villa with a hip problem and will be closely monitored on Thursday and Friday.
Meanwhile, Gayle looks the more likely out of the two to feature at White Hart Lane, despite coming off at half-time against Villa.
It was first thought the striker had aggravated an injury picked up at Swansea City last Saturday, but instead he was feeling unwell.
Palace are confident Gayle will be over his illness in time to lead their attack against Spurs.
